Press the button or shake your phone. But it breaks down easily for unknown reasons. I've tried my best but still can't fix it. Maybe the logic is too complicated, because besides the easier logic of odd and even numbers, the logic of judging the same number of points has become complicated. It has occupied my entire page and started to collapse. Not to mention whether the sum of three dice is more than ten or less than nine. BTW,O is “odd”, E is “even” ,green LED is the dices have the same point.
